'SOLDERING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 668,320, dated February19, 1901. Application filed April 30, 1 900. $eria1No. 14, 998. \Nomodel.)

To all whom it may concern:

Be it known that 1, WILLIAM A. ROSE, a citizen of the United States,residing at Santa Rosa, in the county of Sonoma and State ofGalifornia,have invented certain new and useful Improvements inSoldering Implements, of which the following is a specification.

My invention relates to implements for soldering, by hand, the caps tothe open ends of filled sheet-metal cans. Such an iron, however, isadapted to other uses; but I describe it here in its adaptation to thepurpose for which it is now particularly intended. The irons commonlyused for hand-soldering of this kind are large heavy masses of severalpounds in weight forged to a working edge. The large amount of metal isrequired to retain the heat, since the irons are usually heated byexternal means. When the working edge becomes unfit for use, the massmust be reforged to a new edge, and in this way much time and labor arewasted. I have devised an iron capable of continuous use and with aconstant working edge,which is provided also with means for internalheating and keeping heated.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a perspective View. Fig. 2 is a horizontal section throughthe heating-chamber. Fig. 3 is a vertical cross'section on the line a:a: of Fig. 2.

A represents a hollow chamber, which for can-cap soldering I prefer tomake of the segmental shape shown.

B represents a shank secured to the chamber and having a hollownon-conducting handle G. Entering this handle is a tube D, which isflexible and extends to any suitable source of gas or oil supply. A tubeE, which may be a continuation of the tube D, connects the handle to aburner-hole a in the chamber A. Any suitable nozzle or burner can beused within the chamber. Another hole a is formed in the opposite end ofthe chamber to permit the products of combustion to escape after heatingthe soldering-iron, as hereinafter described.

The front of the chamber A is entirely open, as shown in Fig. 3, and itsfront edges are formed into clips I). Held between these clips is asoldering-iron F, which for this form of soldering is a curved metal barof uniform thickness throughout its length. This thickness should besuch that the edge of the bar is of the proper size to act as asoldering-iron; The curvature of the bar conforms to that of the chamberand also to the curvature of standard sizes of can-caps. When in properposition for operation, as shown in the drawings, the lower edge of thebar projects a short distan ce below the bottom of the chamber, and thebar itself is held in place by set-screws, which pass through thechamber and rest against the edge of the bar. One of such set-- screws(shown at c) is sufficient to hold the soldering-bar rigidly in place.When this screw is loosened, the bar can be adjusted vertically in thechamber and can be continuously used until it is entirely worn out. Itwill be seen that the shortening of the bar produced by wear alwaysleaves a good working edge of the proper thickness, and hence that thenecessity which has heretofore eX- isted of reforging an edge on suchbars is done away with. Further, the curved bar of uniform thicknessshown is exceedingly light and easy to handle when compared with thebars formerly used in which a heavy mass of metal was required in orderto retain heat. By my construction the lower part of the bar is directlyexposed to the action of heat confined within the chamber, whose openside is closed by the bar itself.

I prefer to afford a resistance to the passage of heat through thechamber by providing it with a filling capable of being heated and ofretaining heat, which filling shall be in direct contact with thesolderingbar. This makes a more efiicient heating agency than a jet offlame alone directed into the chamber. For such filling I can use anysuitable material; but in practice I have used and prefer to use blocks,fragments, or pieces of hard carbon G. Such material quickly becomesheated and retains its heat, and as it is disposed in the chamber incontact with the soldering-tool it communicates constant heat to thelatter.

The curved bar shown is particularly adapted for soldering caps uponopen can-heads, but is illustrative of other forms and shapes ofsoldering-bars which may be used in other classes of soldering inconnection with such a heating-chamber as I have described. I do notlimit myself, therefore, to the particular shape of bar nor to the exactdetails of construction or arrangement herein described or 5' shown inthe drawings, as I desire to avail myself of such modifications andequivalents as fall properly within the spirit of my invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. A soldering implement comprising a heating-chamber and burner, asoldering-bar mounted upon said chamber, and a filling of materialwithin the chamber adapted to absorb and communicate heat.

2. A soldering implement comprising an open-sided heating-chamber andburner, a soldering-bar mounted upon said chamber so as to close itsopen side, and a filling of material Within the chamber adapted. toabsorb and communicate heat.

3. A soldering implement comprising a heating-chamber and burner, asoldering-bar mounted upon said chamber, and a filling of carbon withinthe chamber adapted to absorb and communicate heat.

4. A soldering implement comprising a chamber having an open front,means for adnature, in presence of two witnesses, this 9th day of April,1900.
